Effect of Cold Rolling Rate on Mechanical Properties and Texture of 3104 Aluminium Alloy Sheet
The industrial 3104 hot rolled sheets were cold rolled in the range of 84.5%～92.0%by the experimental cold rolling mills.Then,the cold rolled sheets prepared with different cold rolling rates were analyzed and evaluated by mechanical tensile properties test,earing rate test and texture test based on X-ray diffraction(XRD).With the increase of cold rolling rate,the yield strength of the mate-rial increases from 261 MPa to 275 MPa,the elongation decreases from 5.7%to 4.2%,and the earing rate increases from 1.36%to 3.31%.The texture proportion of β-fiber produced by rolling gradually increases,and the cube texture proportion gradually decreas-es.
